You do yourself a disservice in that description. No one is ambitious in 
all things, but in the schematics you provided, your ambition showed 
through there.

Try, but that's the only way to do it unless the hardware was designed 
for it. So your suggestion about using the second core for the 
conversion is still a software solution, an ergo there is an existing 
code base for it with qemu (regardless of which distro you run it on).
